Answer:

The correct option is;

Connect the two circles together using the compass.

Step-by-step explanation:

To draw an inscribed equilateral triangle;

1) Construct the circle

2) The radius of the circle can be drawn from the center of the circle intersecting the circumference

3) With the compass adjusted to the length of the radius, place the compass at the point of intersection of the radius and the circumference and draw arcs around the circumference of the circle

4) Connect every other point where the arc crosses the circumference

5) The figure constructed is n equilateral triangle

Therefore, the correct option is Connect the two circles together using the compass.

The length of a rectangle is increasing at a rate of 1 meter per day and the width is decreasing at a rate of 2 meters per day.

Goshia [24]

Answer:

The area is changing at 2 m²/d.

Step-by-step explanation:

The area of a rectangle is given by:

$A = l*w$

Where:

l is the length

w is the width

We have that the length is increasing at a rate:

$\frac{dl}{dt} = 1 \frac{m}{d}$

And the width is decreasing at a rate:

$\frac{dw}{dt} = -2 \frac{m}{d}$

The change in the rectangle's area is the following:

$\frac{dA}{dt} = w\frac{dl}{dt} + l\frac{dw}{dt}$

When the length is 8 meters and the width is 18 meters we have:

$\frac{dA}{dt} = 18 m*1\frac{m}{d} + 8 m(-2 \frac{m}{d})$

$\frac{dA}{dt} = 18 \frac{m^{2}}{d} - 16 \frac{m^{2}}{d}$

$\frac{dA}{dt} = 2 \frac{m^{2}}{d}$

Therefore, the area is changing at 2 m² per day.

Help me on 5 and 6 plssssss

Alex Ar [27]

For number 5, you just plug -2 into x. We now have g(-2)=3(-2)+1. This gives us g(-2)=-5.

This is the same for 6. h(-6)=-3(-6)-2. This gives us h(-6)=16.

The answer is g(-2)=-5. The other answer is h(-6)=16.

the sides of a rectangle are in the ratio 2:5. if the longer side of the rectangle is 25.5 in., what are it's width, perimeter,

Ad libitum [116K]

Answer: The width of the rectangle is 10.2 inches, the perimeter is 71.4 inches, the area is 260.1 inches.

Step-by-step explanation:

25.5/5=5.1

5.1*2=10.2

The width is 10.2 inches

25.5*2+10.2*2=71.4

The perimeter is 71.4 inches

20.5*10.2=260.1

The area is 260.1
